Ein (アイン Ain) is a bounty hunter affiliated with the Imperial Army who uses an self-made street fighting style called Kenka Kenpou. Initially, he goes after Kenshiro for a reward, but after Bat shows him their corrupt ways and Ken saves his adoptive daughter Asuka, he joins the Hokuto Army.
Ein is a man of average height and a heavily muscular build. He has a rather defined face with somewhat messy and decently long hair and narrow eyes.
He wears a suit that exposes the top of his chest and shoulder pads, both of which are covered in stars and stripes resembling the American flag. He has leather gloves with metallic studs and two belts around his waist. He also has boots that have the same star motif.
Ein is a prideful, but humble man, taking bounties for the happiness of his daughter Asuka rather than for himself. He is shown to be optimistic, and also very confident in his abilities. He is also laid-back, and sometimes comedic around those he trusts.
When Asuka was in danger, he expressed great concern for her well-being.

Kenka Kenpou (ケンカ拳法, lit. "Brawling Marital Arts") is an unorthodox brawling style made by Ein. His attacks consist of heavy punches, or kicks, that allow him to even damage stone walls.
